Should I buy Zerolemon's extended battery or Spigen's Slim Armor View case for the Note 3? They both cost the same and I've been tearing my hair off trying to decide on which to buy. They both add considerable weight, which I like, and bulk, which I am not that fond of, but I can deal with. I like the Spigen Slim Armor View case for adding weight without much bulk, but I like Zerolemon's case+extended battery because it is, in my opinion, the most practical case. Which one should I buy?
